Fig. 6: Steady-state entanglement through EPs.
From: Steering entanglement through exceptional points in non-hermitian cavity magnomechanics
The bipartite entanglement En (where n → (am, mb, ab)) as a function of normalized microwave cavity mode detuning Δa/κa (a) and cavity dissipation κa/γb (b). The blue, red, and black curves represent Eam(photon−magnon), Emb(magnon−phonon), Eab (photon-phonon), respectively. The solid, dashed, and dotted lines indicate that the values of photon-magnon coupling Gma/Δa are 0.5, 1 and 1.5, respectively, which makes the system under the PT symmetry protection and PT broken regimes. Here Γ/ωb = 1.0, while the other parameters used are the same as in Fig. 2.
